note 82988 added to function.readdir

Handy little function that returns the number of files (not directories) that exists under a directory. Choose if you want the function to recurse through sub-directories with the second parameter - the default mode (false) is just to count the files directly under the supplied path. <?php /** * Return the number of files that resides under a directory. * * @return integer * @param string (required) The directory you want to start in * @param boolean (optional) Recursive counting. Default to FALSE. * @param integer (optional) Initial value of file count */ function num_files($dir, $recursive=false, $counter=0) { static $counter; if(is_dir($dir)) { if($dh = opendir($dir)) { while(($file = readdir($dh)) !== false) { if($file != "." && $file != "..") { $counter = (is_dir($dir."/".$file)) ? num_files($dir."/".$file, $recursive, $counter) : $counter+1; } } closedir($dh); } } return $counter; } // Usage: $nfiles = num_files("/home/kchr", true); // count all files that resides under /home/kchr, including subdirs $nfiles = num_files("/tmp"); // count the files directly under /tmp ?> ---- Server IP: 212.63.193.10 Probable Submitter: 83.140.94.180 ---- Manual Page -- http://www.php.net/manual/en/function.readdir.php Edit -- https://master.php.net/note/edit/82988 Del: integrated -- https://master.php.net/note/delete/82988/integrated Del: useless -- https://master.php.net/note/delete/82988/useless Del: bad code -- https://master.php.net/note/delete/82988/bad+code Del: spam -- https://master.php.net/note/delete/82988/spam Del: non-english -- https://master.php.net/note/delete/82988/non-english Del: in docs -- https://master.php.net/note/delete/82988/in+docs Del: other reasons-- https://master.php.net/note/delete/82988 Reject -- https://master.php.net/note/reject/82988 Search -- https://master.php.net/manage/user-notes.php
